Three armed men apparently try to rob an armoured van in Australia's Sydney on Monday. An eyewitness filmed the incident from his phone from a building across the street. The video shows three men approaching the van and appearing to fire shots. But the men then flee to their car, driven by a fourth person, and leave the scene. According to the police, two security guards in the vehicle had refused to hand over the money. One of the two security guards was treated by paramedics.
